Total VersatilityIdeal for a wide range of applications

Powerful and precise, the Komatsu

PC450-8 is equipped to effi ciently

carry out any task your business

requires. On big sites or small, for

digging, trenching, landscaping or

site preparation, the Komatsu origi-

nal equipment hydraulic system

always ensures maximum produc-

tivity and control.

5 working modes

Power, Lifting, Breaker, Attachment,

and Economy.

The PC450-8 features 5 selecta-

ble working modes that optimise

performance and fuel usage. The

Economy mode can be adjusted

for an ideal balance between power

and economy to match your work.

The oil fl ow delivered to hydraulic

attachments is adjustable directly

on the class-leading wide screen

monitor panel.

Built-in versatility

To allow the use of many attach-

ments, such as buckets, breakers

or demolition tools, a power sup-

ply for a hydraulic quick coupler

with adjustable pressure settings,

and an additional hydraulic cir-

cuit controlled by a foot pedal

and a sliding joystick push button

are standard on the PC450-8. A

second optional auxiliary line is

also available for attachments that

require extra hydraulic actuation.

Two-mode boom control

Smooth mode

Boom fl oats upward, reducing lifting of ma-

chine front. This facilitates gathering blasted

rock and scraping down operations.

Power mode

Boom pushing force is increased, ditch

digging and box digging operation on hard

ground are improved.

“Heavy duty” features

The PC450LC-8 HD was designed

to stand up to the hardest working

conditions while still maintaining

maximum performance. Its shorter

boom (6.670 mm) was specially

developed to enhance lift capacity

and productivity in tough loading

applications. Other features of this

“heavy duty” excavator are: stand-

ard full length track roller guards,

double grouser track shoes and

optional OPG top and front guard.

Powerful and Environmentally Friendly

Eco-gauge

Idle caution

Komatsu SAA6D125E-5

Low consumption ecot3 engine

The Komatsu SAA6D125E-5 engine

provides high torque, a better per-

formance at low speed and low fuel

consumption. This ecot3 engine

features a new combustion cham-

ber design with optimised ignition

and combustion timing. The operat-

ing pressure of the new common

rail system was increased for im-

proved injection and fuel effi ciency.

The air-to-air charge cooler reduces

the temperature of the compressed

air supplied by the turbo charger to

the cylinders, and further improves

fuel consumption.

Meets EU Stage IIIA

The new Komatsu ecot3 engine

technology reduces NOx and

particle emissions, fuel consump-

tion and noise level. The Komatsu

SAA6D125E-5 engine is certifi ed for

EPA Tier III and EU Stage IIIA emis-

sion regulations.

Komatsu integrated hydraulic system

The PC450-8 is a highly respon-

sive and productive machine with

all major hydraulic parts designed

and manufactured by Komatsu.

The electronic Closed Load Sens-

ing hydraulic System (CLSS) offers

complete control during individual

or combined movements – without

sacrifi cing performance or produc-

tivity.

Eco-gauge and idle caution

The unique ECO-gauge helps the

operator reduce emissions and fuel

consumption for environmentally

friendly and energy saving opera-

tions. And to further avoid wast-

ing fuel when the machine is not

actually working, a standard-fi t idle

caution is displayed if the engine

idles for 5 minutes or more.

7

Reduced wastage

To avoid spillage of excess grease

– and prolong the life of your

machine – the PC450-8 can be

equipped with an automatic greas-

ing system that provides precisely

the correct amount of grease when

and where it’s required.

8

First-Class Operator Comfort

Hot and cool box

Joysticks with proportional control button for

attachments

Wide spacious cab

The newly designed, wide and

spacious cab includes a heated

air suspension seat with a reclin-

ing backrest. The seat height and

longitudinal inclination are easily

adjusted with a pull-up lever. You

can also set the operational posture

of the armrest and the position of

the console or recline the seat all

the way and place it into a fully fl at

state with the headrest attached.

Low noise design

Komatsu Dash 8 crawler excava-

tors feature the lowest in-class

external noise levels and are

especially well-suited for work in

confi ned spaces or urban areas.

Reduced fan speed, a large capac-

ity radiator, and the optimal usage

of sound insulation and of sound

absorbing materials help to make

noise levels inside Dash 8 excava-

tors comparable to those inside an

executive car.

Pressurised cab

An automatic air conditioner, an air

fi lter and a positive internal air pres-

sure (60 Pa) combine to prevent

external dust from entering the cab.

Cab damper mounting

The built-in stability of the Komatsu

PC450-8, combined with a highly

rigid deck and a sprung multi-layer

viscous mount system, drastically

reduces vibration levels for the

operator.

Automatic air conditioner

9

Large, widescreen TFT monitor

To enable safe, accurate and

smooth work, the user friendly

monitor is the highly intuitive user

interface for the machine’s Equip-

ment Management and Monitoring

System (EMMS). Multilingual and

with all essential information avail-

able at a glance, it features simple

and easy to operate switches and

multifunction keys that provide the

operator with fi ngertip access to a

wide range of functions and operat-

ing information.

10

Highest Safety StandardsSafe SpaceCab™

Specifi cally designed for Komatsu

excavators, the Dash 8 cab has a

tubular steel frame. It provides very

high shock absorbency, impact

resistance and durability. The seat

belt is designed to keep the opera-

tor in the safety zone of the cab

in the event of a roll-over. At your

request, the Komatsu PC450-8 can

also be fi tted with an ISO 10262

Level 2 Falling Object Protective

System (FOPS).

Rear view camera

A standard fi tment camera gives

an exceptionally clear view of the

rear work zone on the wide-screen

monitor panel. Large mirrors on

both sides ensure that machine

visibility meets the latest ISO stand-

ards.

Optimal job site safety

Safety features on the Komatsu

PC450-8 comply with the lat-

est industry standards and work

together as a system to minimise

risks to personnel in and around the

machine. An audible travel alarm

further promotes job site safety.

Very durable anti-slip plates – with

additional high friction covering

– maintain long term traction per-

formance.

Safe and easy maintenance

Thermal guards are placed around

high temperature parts of the

engine. The fan belt and pulleys

are well protected and in case of

damage, fi re risk is reduced by a

pump/engine partition that prevents

hydraulic oil from spraying onto the

engine.

Easy Maintenance

Water separator

This is stand-

ard equipment

which removes

any water that

has become

mixed with the

fuel, preventing fuel system dam-

age.

Easy access to the engine oil fi lter and fuel drain valve

The engine oil fi lter and fuel drain

valve are mounted remotely to im-

prove accessibility.

Side-by-side cooling

Since the radiator, aftercooler and

oil cooler are arranged in parallel, it

is easy to clean, remove and install

them.

Washable fl oor

The fl oor is easy to keep clean.

The gently inclined surface has

a fl anged fl oormat and drainage

holes to facilitate runoff.

Long-life oil fi lters

The hydraulic oil fi lter uses high-

performance fi ltering material for

long element

replacement

intervals, which

signifi cantly

reduces mainte-

nance costs.

Flexible warranty

When you purchase Komatsu

equipment, you gain access to a

broad range of programmes and

services that have been designed

to help you get the most from

your investment. For example,

Komatsu’s Flexible Warranty

Programme provides a range of

extended warranty options on

the machine and its components.

These can be chosen to meet your

individual needs and activities. This

programme is designed to help

reduce total operating costs.
